The present invention describes a system and method for communicating voice and data over a packet-switched network that is adapted to coexist and communicate with a legacy PSTN. The system permits packet switching of voice calls and data calls through a data network from and to any of a LEC, a customer facility or a direct IP connection on the data network. The system includes soft switch sites, gateway sites, a data network, a provisioning component, a network event component and a network management component. The system interfaces with customer facilities (e.g., a PBX), carrier facilities (e.g., a LEC) and legacy signaling networks (e.g., SS7) to handle calls between any combination of on-network and off-network callers. The soft switch sites provide the core call processing for the voice network architecture. The soft switch sites manage the gateway sites in a preferred embodiment, using a protocol such as the Internet Protocol Device Control (IPDC) protocol to request the set-up and tear-down of calls. The gateway sites originate and terminate calls between calling parties and called parties through the data network. The gateway sites include network access devices to provide access to network resources. The data network connects one or more of the soft switch sites to one or more of the gateway sites. The provisioning and network event component collects call events recorded at the soft switch sites. The network management component includes a network operations center (NOC) for centralized network management.

1. A method for transmitting voice information over a packet-switched data network, the method comprising: receiving a signaling message associated with a telecommunications call requested between a caller at an origination location to a callee at a termination location, wherein the caller requests connection of the telecommunications call by dialing a termination call number associated with the termination location; querying a customer profile database using a customer look-up key contained in the signaling message; extracting from the customer profile database a plan for servicing telecommunications calls requested by the caller, wherein the plan specifies at least one process to be performed in response to reception of the signaling message; implementing the plan; analyzing the termination call number to determine a termination gateway servicing the termination location; and connecting the requested telecommunications call between an origination gateway servicing the origination location and the termination gateway. 2. A method as defined in claim 1, wherein the plan specifies verification of an account code in order for the caller to participate in the requested telecommunications call, the implementing act comprising: prompting the caller to input the account code; receiving a response from the caller; and performing the analyzing act and the connecting act if the response matches the account code. 3. A method as defined in claim 1, wherein the plan specifies input of one of a plurality of project account codes associated with a billing account set up for the caller, the implementing act comprising: prompting the caller to input one of a plurality of project account codes; receiving a response from the caller, the response being a specific project account code; and marking the telecommunications call as associated with a specific billing account identified by the specific project account code. 4. A method as defined in claim 1, wherein the analyzing act comprises: determining a least-cost route through the packet-switched network between the origination gateway and the destination gateway. 5. A method as defined in claim 4, wherein the connecting act comprises: allocating an ingress port at an origination access server located at the origination gateway; and allocating an egress port at a termination access server located at the termination gateway, wherein the least-cost route is determined between the ingress port and the egress port. 6. A method as defined in claim 1, wherein the signaling message comprises an out of band signaling format. 7. A method as defined in claim 1, wherein the telecommunications call comprises media traffic, the connecting act further comprising: transmitting the media traffic between the origination gateway and the termination gateway. 8. A method as defined in claim 7, further comprising: converting the media traffic from a first media format to a second media format operable for transmission of the media traffic over the packet-switched data network. 9. A method as defined in claim 8, wherein each of the first and the second media formats are selected from the group consisting of: a circuit switched format and a packet switched format. 10. A method as defined in 9, wherein the media traffic comprises content selected from the group consisting of voice information and data information, wherein the analyzing act comprises: determining whether the media traffic comprises voice information or data information; and wherein the connecting act comprises: terminating the telecommunications call at the the termination gateway via a modem if the media traffic comprises data information; and terminating the telecommunications call at the termination gateway via an RTP connection if the media traffic comprises voice information.
